# UpdateChannelParams defines a rpc handler method for MsgUpdateParams.

`POST /ibc.core.channel.v1.Msg/UpdateChannelParams`

## Request body

- object — MsgUpdateParams is the MsgUpdateParams request type.
  - `authority` string — authority is the address that controls the module (defaults to x/gov unless overwritten).
  - `params` object — params defines the channel parameters to update. NOTE: All parameters must be supplied.
    - `upgrade_timeout` object — Timeout defines an execution deadline structure for 04-channel handlers. This includes packet lifecycle handlers as well as the upgrade handshake handlers. A valid Timeout contains either one or both of a timestamp and block height (sequence).
      - `height` object — Normally the RevisionHeight is incremented at each height while keeping RevisionNumber the same. However some consensus algorithms may choose to reset the height in certain conditions e.g. hard forks, state-machine breaking changes In these cases, the RevisionNumber is incremented so that height continues to be monitonically increasing even as the RevisionHeight gets reset
        - `revision_number` string, uint64
        - `revision_height` string, uint64
      - `timestamp` string, uint64
